Apply for a Billerica Permit in Six Clear Steps
Confirm the permit and zoning path
Describe the exact work, location, size and systems affected. Exterior structures, added living space and business uses need zoning review before construction documents are finalized.
Collect the Billerica-required documents
Do not upload one generic plan for every project. Additions and new homes need three Fire-stamped plan sets; decks and sheds need two sets; pools, solar and demolition each have separate checklists.
Open the town-linked online portal
Create or sign into the permitting system and choose building, electrical, gas, plumbing or sheet metal. Use a separate application for each structure when required.
Enter complete site and contractor information
Use the correct property address, assessor plate/parcel, owner, licensed Construction Supervisor, HIC information, workers’ compensation status, project description, estimated value and debris-disposal details.
Upload coordinated, readable files
Make the application, signed contract, plot plan, floor plans, elevations, structural calculations and trade-permit scope describe the same project.
Respond to comments and wait for issuance
Check the application account and messages. Correct every review item, pay the official fee when instructed and confirm the permit is issued before work begins.

Billerica Accessory Dwelling Units: Start With the 2025 Town Guide
Maximum protected size
The town guide states an ADU may not exceed 900 square feet or half the gross floor area of the principal dwelling, whichever is smaller.
Gross floor area includes all stories, including basements.
Owner occupancy
The guide says owner occupancy is not required. The protected route does not cover creation of an ADU for short-term-rental use.
Attached or detached
An ADU may be attached or detached on the same lot as the principal dwelling, subject to dimensional, building, fire and other requirements.
ADU checkpoint | Billerica-specific question |
|---|---|
Zoning district | Is a single-family dwelling allowed by right or special permit in this district? |
Bulk rules | Does the attached or detached ADU meet the same setback, lot-coverage and height rules as other structures in the district? |
Water, sewer and driveway | Are DPW permits needed for service changes, a new driveway or sewer connection? |
Wetlands | Does an addition or detached unit fall within local or state wetland jurisdiction? |
Fire separation and egress | Are rated separations, code-compliant egress and interconnected alarm changes required? |

Search Billerica Permits Without Mixing Up the Two Portals
Use Online Permitting to manage an application
Use the application portal to create or work with an online permit account.
Use Permit Report for public permit information
Use the town-linked report page when researching issued permits or property history.
Search by permit number first
Use the exact number from a permit card, invoice, contractor email or inspection notice.
Search the property address
Try the base address before adding unit or building details. Confirm the parcel through the interactive map.
Do not assume a permit is closed
Check whether required building, electrical, plumbing, gas and sheet-metal finals are complete.
Ask for the missing document
Contact the Building Department when you need approved plans, a correction letter, inspection history, certificate or a record not shown in the public report.
“I am checking permit [number] at [address]. Please tell me which building or trade inspection remains open, whether the permit is expired, and what the current owner must provide to close it.”
Get Business-Use Approval Before Signing a Lease or Renovating
Building Department
The town FAQ directs a new business to complete a business-use approval form to verify that the intended use is allowed in the zoning district.
Planning and ZBA
Site-plan, use special permit, variance or other public-board review may be required before the building permit.
Other approvals
Fire, Health, Select Board, Town Clerk, Conservation and DPW permits may apply depending on use and site work.
Screen Demolition for Billerica’s Preservation Delay
Permit-package basics
- Building permit application
- Certified plot plan
- CSL/HIC or homeowner affidavit
- Workers’ comp affidavit
- Signed contract/owner signature
- Proof utilities are shut off
Historical review risk
Billerica’s general bylaws provide a review process for significant buildings. A building found “preferably preserved” can face a six-month demolition-permit delay while preservation alternatives are pursued.
Start this check early.
Know Which Permits a Homeowner Can Pull
Permit | Who may obtain it under the town FAQ? | What to prepare |
|---|---|---|
Building | A qualifying homeowner may pull it after completing the homeowner exemption form | Homeowner affidavit, workers’ comp affidavit, plans, plot plan and owner signature as applicable |
Electrical | Massachusetts-licensed electrician | License and project/equipment details |
Plumbing/gas | Person licensed by Massachusetts for the plumbing/gas work | License, fixture/appliance details and scope |
Fix Common Billerica Permit Problems
Problem | Likely cause | Best next action |
|---|---|---|
Portal cannot find address | Address or parcel format mismatch | Confirm parcel in Billerica GIS; use base address; call office if still missing |
Addition application returned | Missing certified plot, Fire-stamped plans, HERS or engineering | Compare the upload against the town’s addition checklist |
“Plot plan” rejected | Mortgage inspection plan submitted | Obtain the required certified plot plan from prior closing files, town records or a surveyor |
Inspection not on schedule | Voicemail not confirmed or insufficient notice | Call the correct discipline and wait for inspector confirmation |
Public report shows permit but no closure | Missing trade or final inspection | Ask Building to identify the exact open discipline and reactivation path |
Shed location fails zoning | Wrong setback for shed size or another lot constraint | Bring certified plot plan and shed dimensions to a Building Inspector |
Business cannot receive occupancy approval | Use not approved or other department signoffs incomplete | Return to business-use approval and list every outstanding board/department condition |
ADU design stalls | Size, district, setbacks, wastewater, wetlands, fire separation or egress conflict | Use the current ADU guide and hold a pre-application discussion before revising plans |

Use the Town of Billerica-linked Mapsonline permitting portal. The town lists online applications for building, electrical, gas, plumbing and sheet-metal permits.
How do I search for an existing Billerica permit?

How do I schedule a Billerica building inspection?

When is a certified plot plan required?
The department FAQ says a plot plan is required when any structure or living space is added. Billerica’s project checklists require certified plot plans for additions, decks, sheds, new construction, detached garages, accessory structures, pools and demolition. Mortgage inspection plans are not accepted for the listed packages.
What are Billerica’s shed setbacks?
The town FAQ says a shed of 100 square feet or less may be in a side or rear yard with a 7-foot-6-inch side setback and 10-foot rear setback. A shed over 100 square feet requires a 15-foot side setback and 20-foot rear setback. Other lot constraints may still apply.
Can a Billerica homeowner pull their own permits?
A qualifying homeowner may pull a building permit after completing the homeowner exemption form. The town FAQ says electrical permits must be obtained by a Massachusetts-licensed electrician and plumbing/gas permits by a person licensed by the Commonwealth for that work.
How much is a Billerica residential building permit?
The current town-linked schedule lists $12 per $1,000 of estimated construction cost with a $40 residential minimum. The schedule uses a $250-per-square-foot valuation basis for construction/demolition and states that a $30 processing payment is made at application and deducted from the total fee owed.
What does Billerica require for a deck or shed permit?
The residential checklist requires a completed application, certified plot plan, CSL/HIC or homeowner affidavit, workers’ compensation affidavit, two sets of building plans and a signed contract or homeowner signature.
Can I create an ADU in Billerica?
Billerica’s current ADU guide describes attached and detached units with a maximum of 900 square feet or half the principal dwelling’s gross floor area, whichever is smaller. Owner occupancy is not required, but zoning district, setbacks, DPW, wetlands, fire separation, egress and other rules still apply.
What should I do before opening a business in Billerica?
The town FAQ directs applicants to the Building Department for a business-use approval form to verify that the proposed business is allowed in the zoning district. Complete this before relying on a lease or beginning renovations.
